Focus Lens

SIL optics technology Co., all use CVD Znse, which imported-from USA, materials absorption is lower, our lens can with stand the high power density, and surface is firm, not easy to fall off, resistance to wipe.

Zinc selenide focus lens are widely used in CO2 laser process, including cutting, drilling, carving & other laser system. With the imported material, our products can withstand high power density; and the film is solid, with which the lens are resistant to wipe. Because of the double-side film, the filterability of the light (the wavelength is 10.6μm) can reach 99%.

Reflective Mirror

CO2 Laser Mirror

REFLECTIVE MIRROR

Reflect mirror is one of the most important elements in light transmission system, it can be used as tail mirror and folding mirror in laser cavities, outside the cavities, it plays the role of light-bent machine. Mirrors can be made by various materials.
Mo mirror can be used in harsh environment, also for a long time, can stand high-power and resistant to wipe, but the reflectivity is not so high.
Silicon is used most as the material of mirror, it cost lower, durable, and with stable thermal properties. With gold plated and protection film on the gold, the surface is difficult to be damaged, it also enhance the reflectivity and durable. The fold-plated silicon mirror can stand high –power irradiancy.

Reflect Mirror

Reflect mirrors mainly material are molybdenum and silicon. Si is the most common material, its superiority are low cost, strongly Durability and thermal stability. Mo mirror surface is high intensity; it is ideal material which can be applicable to variety of harsh physical environment. Mo mirror usually is un-coating.

Scan Lens

scan lens11

 

CO2 laser system scan lens and light expander are widely used in laser marking, engraving, drilling machines, etc.

The single-chip flat-field Scanning Mirror of  SIL has optimized the wide-angle and long focal-length light path, it is widely applied in wide scan range situation.
The absorb ability of Zinc Selenide to the infrared wavelengths is low, and can flitter visible light; it is the top choice of beam expander lens.

Beam Combiner

Beam combiner

 

 

Beam combiner combines the outputs of multiple laser sources (often in the form of laser arrays) to obtain a single output beam. The use of a scalable beam-combiner leads to a power-scalable laser source, even if the single lasers are not scalable.

Beam Splitter

Beam splitter

 

 

Beam splitters can make part of the light through the lens. and reflects the remaining light. The main application is bisected laser light to the ratio of 50 : 50 Common beam splitters is used to separate or merge the laser beam. The polarized beam splitters are used to split or merge the two orthogonal polarization States of the laser beam. The beam splitter performance major determinant of its coating properties.

YAG Laser Assembly

YAG lens

er

YAG laser has been widely used in material processing, such as cutting, drilling, welding, etc, which not only improves the quality of the work pieces, but also the work efficiency. With Nd: YAG crystal’s excellent thermal performance, the laser’s reliability, efficiency, and power has been enhanced a lot. So it is widely used in laser rangefinder, laser radar, laser industrial processing, laser medical fields, etc. Besides that, it also provides a quick and precious method for scientific research.

Rods

YAG rods

In all Laser equipment laser rod acts as a very important role. Whether in industrial, medical laser equipment or military laser equipment. laser rods play a very important role.
Nd: YAG is cubic crystal, it is isotropic crystal. Nd: YAG is a four-level system, high quantum efficiency, broad stimulated emission area, so the threshold is much lower than ruby and neodymium glass. Also, because the Nd: YAG crystal has excellent thermal properties, it is ideal crystal for continuous and heavy-frequency devices. Nd: YAG crystal is able to work continuously at room temperature, the only solid working substances in low and medium-power pulse devices, the current application of Nd: YAG is much more broader than any other substances.
Nd: YAG ROD is the most mature and widely used as solid-state Laser material, adopted by R&D, medical, industrial and military customers. Its main and obvious advantages are: high gain, low threshold, high efficiency, low loss at 1.064 μm, as well as high optical quality, good thermal conductivity and thermal shock characteristics, stable chemical and mechanical properties, which make Nd: YAG as the most suitable and commercial laser material for various modes of operation (CW, pulsed, Q-switched, mode locked and cavity dumped).

Dimension

The most commonly used size of the Nd: YAG Laser rod diameter Is from1.5 mm to 18.0 mm, 0.5 mm up by ladder. length size

from 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 70 mm to 200 mm.

we can use diameter and  length as a combination of the size.
